Ah, yeah of course... I totally forgot about that.
If it had been puts(*[1,2,3...]) I wouldnt have asked that question :/
Actually, I'm using this feature a lot in my codes. But didn't know it takes any object, 
which responds to #to_a

Thank you :)

(Okay, I forgot, that puts can take multiple arguments, too. Sometimes, Ruby is just too easy)
